pthread_attr_setdetachstate, pthread_attr_getdetachstate - set and get detachstate attribute
#include <pthread.h> int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate); int pthread_attr_getdetachstate(const pthread_attr_t *attr, int *detachstate);
The detachstate attribute controls whether the thread is created in a detached state. If the thread is created detached, then use of the ID of the newly created thread by the pthread_detach() or pthread_join() function is an error.The pthread_attr_setdetachstate() and pthread_attr_getdetachstate(), respectively, set and get the detachstate attribute in the attr object.
The detachstate can be set to either PTHREAD_CREATE_DETACHED or PTHREAD_CREATE_JOINABLE. A value of PTHREAD_CREATE_DETACHED causes all threads created with attr to be in the detached state, whereas using a value of PTHREAD_CREATE_JOINABLE causes all threads created with attr to be in the joinable state. The default value of the detachstate attribute is PTHREAD_CREATE_JOINABLE .
Upon successful completion, pthread_attr_setdetachstate() and pthread_attr_getdetachstate() return a value of 0. Otherwise, an error number is returned to indicate the error.The pthread_attr_getdetachstate() function stores the value of the detachstate attribute in detachstate if successful.
The pthread_attr_setdetachstate() function will fail if:
- [EINVAL]
- The value of detachstate was not valid
These functions will not return an error code of [EINTR].
